Abstract
Average bond energy values have been calculated for the oxides of Bi, V, U, Y, Nb, Zr, Ti, W, Ta, Al, Hf, and Si from the appropriate thermochemical data. An attempt has been made to explore the influence of these bond energies on the magnitude of kinetic parameters for the anodic oxide growth on the corresponding metals. It has been concluded that, in general, with increasing bond energy, the field required for sustaining a given ionic current density tends to increase, as also does the “Tafel slope.” Further, the magnitude of the “activation dipole” in Dignam's theory, both for the steady‐state and the transient kinetics, tends to decrease with increase in bond energy. Interrelationship of these correlations has been briefly pointed out.
